Dissemination:
We inform all the users that the ftp dissemination of the Geophysical Data Records (S/I/GDRs for Jason-1, Jason-2, Jason-3, Saral  and OGDRs for Saral) products has been transferred to the authenticated AVISO+ ftp portal  (ftp://ftp-access.aviso.altimetry.fr/). It is thus foreseen to stop the previous access (ftp://avisoftp.cnes.fr/AVISO/pub/) by September 12th. 

Note that the deliveries on the Online Data Extraction Service (ODES) and the AVISO+ Cnes Data Center remain unchanged.

Current data:
Since June 20th, the operational chain has been delivering the data for the current missions on both AVISO+ ftp portals, allowing the operational users to switch to the authenticated AVISO+ ftp server as soon as possible. 
The double dissemination is  until 12th  September 2019.

Historical data
:
 The whole historical data on the authenticated Aviso+ ftp portal (ftp://ftp-access.aviso.altimetry.fr) has been transfered.

Thus, the same data is available on both portals until 
September 12th. After September 12th, the Geophysical Data Records products will be available only at the authenticated Aviso+ ftp portal (ftp://ftp-access.aviso.altimetry.fr/)
